Looking around at monitors and I can see this is just as difficult as choosing an interface. For reference, I'm hoping to keep the price for a good pair down to around $400. If anyone has recommendations for any monitors that were top of the line years back and are now pretty affordable, that'd help me break out of the "settling for low quality due to budget" issue I have I think. Although it almost feels like everything I look at is expensive no matter how old.
I'm not 100% set on buying used, but I don't have any big time music stores near me that'd sell monitors so it's mostly what I'm eyeing for now.
